1
Distribution of Data
We can use the shape of a graph to determine how the data is distributed.
2
Normal Distribution
Also known as symmetric or bell shaped. This is when the graph is split in half and both sides look identical.
3
Positively Skewed
Also known as Skewed to the RIGHT.
This is when the data has a "Tail" on the right side of the graph.
4
Negatively Skewed
Also known as Skewed to the LEFT.
This is when the graph has a "Tail" to the left.
5
Uniform
This is when the graph looks the same and the data is evenly spread out. There are no high peaks and it will make a somewhat rectangular shape.

Stem and Leaf Plots
These can be skewed as well
You want to imagine turning the chart to it's side and seeing if it has a "Tail" to the left or right.
The picture shows an example of a positive skew (skew to the right)
